Participation reward: 2 Wealth. Reward for a basically correct answer: 9 wealth. (Multiple-choice question) Question: Which of the following statements regarding the value traceability system are correct? A. Traceability of measurement values refers to the property that enables the values of measurement results or measurement standards to be linked to a specified reference standard (usually a **metrological benchmark or international metrological benchmark**) through an unbroken chain of comparisons with defined uncertainties. B. The main technical methods for achieving traceability of measurement values are calibration and correction. C. A traceability diagram provides a quantitative description of the quantity in question and the chain of comparisons used by the measuring instruments, serving as evidence for the traceability of the measurement values. D. Achieving traceability of measurement values ensures the technical accuracy and consistency of measurements. E. When measurement values originate from multiple sources or through multiple pathways, it inevitably leads to confusion both technically and in terms of management. Answers: ACDE. The main methods for achieving traceability of measurement values are calibration and verification; therefore, statement B is incorrect
A. Traceability of measurement values refers to the property that enables the values of measurement results or measurement standards to be linked to a specified reference standard (usually a **metrological benchmark or international metrological benchmark**) through an unbroken chain of comparisons with defined uncertainties. C. A traceability diagram provides a quantitative description of the quantity in question and the chain of comparisons used by the measuring instruments, serving as evidence for the traceability of the measurement values. D. Traceability of measurement values ensures technical guarantees for the accuracy and consistency of measurements. E. When measurement values originate from multiple sources or pathways, it inevitably leads to confusion in terms of technology and management
